Video-assisted thoracic surgery (VATS) has significantly developed over the last decade. However, a VATS approach for thymoma remains controversial. The aim of this study was to evaluate the feasibility of VATS thymectomy for the treatment of early-stage thymoma and to compare the outcomes with open resection.

sSec_2">Methods

spar0010">A comparative study of 59 patients who underwent surgical resection for early stage thymoma (VATS: 44 and open resection: 15) between 1993 and 2011 was performed. Data of patient characteristics, morbidity, mortality, length of hospital stay, the relationship between miasthenia gravis-thymoma, recurrence, and survival were collected for statistical analysis.

sSec_3">Results

spar0015">Thymomas were classified according to Masaoka staging system: 38 in stage I (VATS group: 29 and open group: 9) and 21 in stage II (VATS group: 15 and open group: 6). The mean tumor size in the open group was 7.6 cm (13&ndash;4 cm) and in the VATS group 6.9 cm (12&ndash;2.5 cm). The average length of stay was shorter in the VATS group than in the open group (P<.001). No significant differences were found in the estimated recurrence-free and overall 5-year survival rates (96% vs 100%) between the 2 groups.

sSec_4">Conclusions

spar0020">VATS thymectomy for early-stage thymoma is technically feasible and is associated with a shorter hospital stay. The 5-year oncological outcomes were similar in the open and VATS groups.
